Here are the solutions for the fraction problems:

Part a· 2 steps

  1. Add the numerators.

    25+45=2+45=65\frac{2}{5} + \frac{4}{5} = \frac{2+4}{5} = \frac{6}{5}
  2. Convert the improper fraction to a mixed number.

    65=115\frac{6}{5} = 1\frac{1}{5}

    The answer is 115\boxed{\mathbf{1\frac{1}{5}}}.

Part b

129\mathbf{1\frac{2}{9}}

  1. Add the numerators.

    59+69=5+69=119\frac{5}{9} + \frac{6}{9} = \frac{5+6}{9} = \frac{11}{9}
  2. Convert the improper fraction to a mixed number.

    119=129\frac{11}{9} = 1\frac{2}{9}

    The answer is 129\boxed{\mathbf{1\frac{2}{9}}}.

Part c

14\mathbf{\frac{1}{4}}

  1. Subtract the numerators.

    34−24=3−24=14\frac{3}{4} - \frac{2}{4} = \frac{3-2}{4} = \frac{1}{4}

    The answer is 14\boxed{\mathbf{\frac{1}{4}}}.

Part d

115\mathbf{1\frac{1}{5}}

  1. Add the numerators.

    710+510=7+510=1210\frac{7}{10} + \frac{5}{10} = \frac{7+5}{10} = \frac{12}{10}
  2. Convert the improper fraction to a mixed number.

    1210=1210\frac{12}{10} = 1\frac{2}{10}
  3. Simplify the fraction part.

    1210=1151\frac{2}{10} = 1\frac{1}{5}

    The answer is 115\boxed{\mathbf{1\frac{1}{5}}}.

Part e

113\mathbf{1\frac{1}{3}}

  1. Add the numerators.

    56+36=5+36=86\frac{5}{6} + \frac{3}{6} = \frac{5+3}{6} = \frac{8}{6}
  2. Convert the improper fraction to a mixed number.

    86=126\frac{8}{6} = 1\frac{2}{6}
  3. Simplify the fraction part.

    126=1131\frac{2}{6} = 1\frac{1}{3}

    The answer is 113\boxed{\mathbf{1\frac{1}{3}}}.

Part f

147\mathbf{1\frac{4}{7}}

  1. Add the numerators.

    57+67=5+67=117\frac{5}{7} + \frac{6}{7} = \frac{5+6}{7} = \frac{11}{7}
  2. Convert the improper fraction to a mixed number.

    117=147\frac{11}{7} = 1\frac{4}{7}

    The answer is 147\boxed{\mathbf{1\frac{4}{7}}}.
